Skeletal Muscle Mitochondrial Protein Synthesis and Respiration Increase With Low-Load Blood Flow Restricted as Well as High-Load Resistance Training

Frontiers in Physiology, 2018
Purpose: It is well established that high-load resistance exercise (HLRE) can stimulate myofibrillar accretion. Additionally, recent studies suggest that HLRE can also stimulate mitochondrial biogenesis and respiratory function.

Mass spectrometry of 1,2,5-oxadiazole N-oxide derivatives: use of deuterated analogues in fragmentation pattern studies

Journal of the Brazilian Chemical Society, 2004
This paper reported on the study of fragmentation pattern in mass spectrometry of 1,2,5-oxadiazole N-oxide derivatives involving deuterium-labeled analogues to identify some critical fragmentations.

Hydro- and deutero-deamination of primary amines using O-diphenylphosphinylhydroxylamine

Nature Communications
While selective defunctionalizations are valuable in organic synthesis, hydrodeamination of primary amines poses challenges. Deuterodeamination, analogous to hydrodeamination, presents even greater difficulties due to its frequently slower deuteration ...

Insights from quasi-in situ cryogenic-transfer atom probe tomography for analyzing hydrogen diffusion in metallic alloys

npj Materials Degradation
Understanding hydrogen embrittlement mechanisms requires insights into nanoscale hydrogen isotope segregation in materials. Cryogenic-transfer atom probe tomography (APT) can provide this insight, if the sample exposure is precisely controlled. Therefore,

Proteomics and lipids of lipoproteins isolated at low salt concentrations in D2O/sucrose or in KBr

Journal of Lipid Research, 2008
There is much interest in the significance of apolipoproteins and proteins that are noncovalently associated with lipoproteins. It is possible that the high ionic strength used for isolation of lipoproteins with KBr and NaI could alter the pattern of ...

Deuterium magnetic resonance imaging of tumors using low-dose systemic deuterated water labeling

Frontiers in Oncology
BackgroundAlthough systemic 2H2O labeling is an attractive clinically relevant strategy for enhancing tumor imaging given relative ease of administration, gradual, slow ramp-up of labeling is preferable to avoid side effects, such as nausea and dizziness.

Body water compartments during bed rest: Evaluation of analytical methods [PDF]

Nine healthy young men were studied to determine the reproducibility and interchangeability of the use of radio-iodinated human serum albumin and Evans Blue dye for estimating plasma volume, sodium bromide for extracellular fluid volume, and deuterium ...

Radical Cascade Combining Cross‐Olefin Coupling with the Smiles‐Truce Rearrangement

Angewandte Chemie International Edition, EarlyView.
We present a cobalt‐catalysed radical cascade that efficiently merges two alkene starting materials to form multiple bonds in a single step. The process begins with a cobalt‐catalysed hydrogen‐atom transfer‐to a styrene double bond, followed by a Giese addition.

Exploring Infant Size and Body Composition at 18 Months: An Ambidirectional Peri‐Urban South African Cohort Study

Maternal and Child Nutrition
The first 1000 days of life lay the foundations for subsequent growth. This ambidirectional study, including prenatal, perinatal and postnatal factors, aimed to identify exposure variables affecting body size and composition and corresponding Z‐score ...

Deuterated water (2H2O, heavy water) labelling to investigate human cell dynamics in vivo - lessons in protocol design and toxicity from the current literature

Frontiers in Immunology
The use of deuterated water (also known as ‘heavy water’) as a tracer to measure human in vivo cell proliferation rates for specific cell subsets has expanded significantly in recent years.
